Although PPT have a place in the classroom, we must always remember that they are a tool, not the teacher! PPTs can be educational and engaging, but many instructors do not have training in how to create one or how to teach from one. I certainly made my share of mistakes in the beginning. It is amazing what you can do with type of presentation, but like the lecture said, you have to be comfortable and know what is beneficial and what is not. Curriculum should be designed by a team of teachers so that the best of the best is obtained and not something that is too wordy, no pictures and minimal engagement. Pictures or inserting video clips keep the slides interesting. I think putting in scenarios is also effective, it takes the attention away from the PPT and creates conversation.
